Android Studio：下载 chaquopy-libgfortran 时出错

Question

我尝试使用 Chaquopy 在我的 Android 应用程序上使用 Python。但我有一些错误，如下所示。我不知道出了什么问题，因为错误没有显示任何内容。我在 pip install 时做错了什么吗？还是有其他方法可以完成此任务？

这是我的项目中使用的build.gradle文件，我认为它没有任何问题。

      python {
        version "3.8"
        buildPython "C:/Users/Kezia/AppData/Local/Programs/Python/Python38/python.exe"
        pip{
          install "numpy"
          install "opencv-python"
        }
      }

Answer 1

我发现了问题，因为我使用的 gradle 版本 8.4 似乎还不支持 Chaquopy。所以我使用 gradle 8.3 版本，它现在可以工作了。
